Objective To explore the imaging features of external iliac artery-related postpartum hemorrhage, and to discuss its interventional therapy measures. Methods The clinical data and imaging findings of one patient with external iliac artery-related postpartum hemorrhage was retrospectively analyzed. The patient received interventional therapy at the intervention department of Shanxi provincial people ’s hospital. The relevant academic papers published in medical literature were reviewed. The common features of this condition were summarized, and the imaging features and the interventional therapy measures were discussed. Results A total of 4 patients, including authors’ case, with external iliac artery- related postpartum hemorrhage were reported in China. Of the 4 case , right external iliac artery-related postpartum hemorrhage was seen in 2 and bilateral external iliac artery-related postpartum hemorrhage was seen in other two. Embolization therapy of three abnormal branches of deep circumflex iliac artery that participated in the uterine blood supply was carried out. Immediately after the embolization the bleeding stopped. Conclusion For the treatment of postpartum hemorrhage, uterine arterial embolization should be followed by abdominal aorta angiography so as to check the external iliac artery. When recurrent bleeding occurs after uterine arterial embolization, the possibility that the abnormal branches of external iliac artery participates in the uterine blood supply should be considered. In performing the embolization of abnormal branches of external iliac artery, the catheter should be inserted to the distal end of the target vessel. Under DSA monitoring the embolic agent should be slowly injected into the targeted artery and the patient should be kept under close observation for blood reflux. Usually, the embolization of abnormal branches of external iliac artery will not cause ischemic symptoms of the pelvis and distal limbs.

The metabolic characteristics of ligustrazin (TMPz) in liver microsomes were investigated in the present study. The reaction phenotyping of TMPz metabolism was also identified by in vitro assessment using recombinant human cytochrome P450 enzymes (CYP) and UDP glucuronosyltransferases (UGT). TMPz was incubated at 37 degrees C with human (HLM) and rat liver microsomes (RLM) in the presence of different co-factors. The metabolic stability and enzyme kinetics of TMPz were studied by determining its remaining concentrations with a LC-MS/MS method. TMPz was only metabolically eliminated in the microsomes with NADPH or NADPH+UDPGA. In the HLM and RLM with NADPH+UDPGA, t1/2, K(m) and V(max) of TMPz were 94.24 +/- 4.53 and 105.07 +/- 9.44 min, 22.74 +/- 1.89 and 33.09 +/- 2.74 micromol x L(-1), 253.50 +/- 10.06 and 190.40 +/- 8.35 nmol x min(-1) x mg(-1) (protein), respectively. TMPz showed a slightly higher metabolic rate in HLM than that in RLM. Its primary oxidative metabolites, 2-hydroxymethyl-3, 5, 6-trimethylpyrazine (HTMP), could undergo glucuronide conjugation. The CYP reaction phenotyping of TMPz metabolism was identified using a panel of recombinant CYP isoforms (rCYP) and specific CYP inhibitors in HLM. CYP1A2, 2C9 and 3A4 were found to be the major CYP isoforms involved in TMPz metabolism. Their individual contributions were assessed b) using the method of the total normalized rate to be 19.32%, 27.79% and 52.90%, respectively. It was observed that these CYP isoforms mediated the formation of HTMP in rCYP incubation. The UGT reaction phenotyping of HTMP glucuronidation was also investigated preliminarily by using a panel of 6 UGT isoforms (rUGT). UGT1A1, 1A4 and 1A6 were the predominant isoforms mediated the HTMP glucuronidation. The results above indicate that the metabolism of TMPz involves multiple enzymes mediated phase I and phase II reactions.

Objective To establish a uremic apoE-/- mouse model to observe serum biochemical parameters and features of aortic root atherosclerosis (AS) in the model. Methods A uremic model was induced surgically in apoE-/- mice: electrocautery of the right kidney at 8 weeks of age and nephrectomy (NX) of the left one 2 weeks later. Control mice were sham-operated. Two weeks after NX, renal functions were detected in the uremic and control mice to evaluate the efficiency of the model. After 10 weeks of NX, blood samples were taken to determine serum biochemical parameters, and aortic root was collected for frozen sections to investigate the lesion features of AS. Results Two weeks after NX, renal functions declined significantly in the uremic mice compared with the control ones, and remained stable 8 weeks later either in males or in females. Ten weeks after NX, serum levels of TCH, TG and LDL-C were dramatically higher in the uremic mice than in the controls, whereas no differences in serum HDL-C or glucose concentration were found between the two groups. Aortic root plaque relative area increased significantly in the uremic mice compared with the controls either in males or in females; more-over, the lesion area was larger in female mice than in male ones. Conclusion We established a uremic apoE-/- mouse model successfully, and this model is characterized by accelerated atherogenesis which is associated with an increase in serum lipid profile. This experimental model can be a useful tool to study the pathogenesis and therapeutic strategies of uremic AS.

OBJECTIVETo explore surface roughness of bone cement and surround tissue on histological characteristic of induced membranes.
METHODSBone cements with smooth and rough surface were implanted in radius bone defect, intramuscular and subcutaneous sites of rabbits, and formed induced membranes. Membranes were obtained and stained (HE) 6 weeks later. Images of membrane tissue were obtained and analyzed with an automated image analysis system. Five histological parameters of membranes were measured with thickness,area,cell density,ECM density and microvessel density. Double factor variance analysis was used to evaluate the effect of the two factors on histological characteristics of induced membranes.
RESULTSMembranes can be induced by each kind of bone cement and at all the three tissue sites. In histological parameters of thickness,area and micro vessel,there were significant differences among the membranes induced at different tissue sites (P = 0.000, P = 0.000, P = 0.000); whereas, there were no significant differences in histological parameters of cell density and ECM density (P = 0.734, P = 0.638). In all five histological parameters of membranes, there were no significant differences between the membranes induced by bone cements with different surface roughness (P = 0.506, P = 0.185, P = 0.883, P = 0.093, P = 0.918).
CONCLUSIONSurround tissue rather than surface roughness of bone cements can affect the histological characteristics of induced membranes. The fibrocystic number, vascularity, mechanical tension and micro motion of the surround tissue may be closely correlated with the histological characteristics of induced membranes.
